Iikhrimu ezimhlophe, iimaski zobuso, izithambiso zokunakekela ulusu, iidayi zeenwele… Kule mihla, kukho iintlobo ngeentlobo zeemveliso zokuthambisa kwimarike kwaye zivela ngokungapheliyo, ezithandwa kakhulu ngabathandi bobuhle.Nangona kunjalo, izinto zokuthambisa zazisetyenziselwa ukukhathalela ulusu kunye nokuhombisa ulusu kunye nokucoca xa zisetyenziswa emzimbeni womntu.Nangona kunjalo, ukhuseleko lwezithambiso luyimfuneko ebaluleke ngakumbi kunokusebenza.Kungenjalo, xa umzimba womntu udibana nezithambiso ezikumgangatho ophantsi ongafanelekanga, iingozi ezahlukeneyo zomzimba nezengqondo ezinje nge-allergies, ukulahleka kweenwele, ukonakala, kunye ne-carcinogenesis.

Ngenxa yoku, iinkampani ezininzi zezothambiso zamasebe e-R&D kunye neelabhoratri ezinxulumene namasebe okuhlola umgangatho ziya kuvavanya izithako zemveliso yezinto zokuthambisa, izinto zokupakisha, iimveliso ezigqityiweyo, kunye neemveliso ezigqityiweyo.Kuphela emva kokuvavanya umgangatho kunye nokhuseleko ngokuhambelana nemigangatho efanelekileyo yokulawula umgangatho apho kunokuthi kukhutshwe isatifikethi sesiqinisekiso semveliso.Ingabonwa ukuba ukuchongwa kunye nokuvavanywa kwezithambiso kwibhubhoratri kuye kwaba ngumqobo wokuqala wokukhusela impilo kunye nokhuseleko lwabathengi.
Ke, yeyiphi imixholo ephambili yovavanyo lokhuseleko lwezithambiso?

Kumenzi wezinto zokuthambisa oqhelekileyo, uvavanyo lwentsimbi enzima, uvavanyo lwemicrobial, uvavanyo lokugcinwa, uvavanyo lomxholo wezinto ezisebenzayo, kunye nezinye izinto ezithintelweyo nezithintelweyo zixhaphake kakhulu kuvavanyo lwetyhefu kunye nohlalutyo.Thatha intsimbi enzima yokulandelela ikhromium njengomzekelo: chromium, chromic acid, metallic chromium, kunye nehexavalent chromium azikho ngokuthe ngqo kwizinto zokuthambisa.Nangona kunjalo, kwinkqubo yokuvelisa izithambiso kunye nophuhliso, kukho i-chromium-equlethe iikhompawundi zokungcolisa kwizikhongozeli zeglasi, ezifana ne-Cr6 +.Oku kufuna iilabhoratri ukuba zenze ukuzimisela kunye nohlalutyo, kwaye emva koko zicebise izisombululo.

Nangona kunjalo, uhambo lokuvavanya umgangatho kunye nokhuseleko lwezithambiso elabhoratri alupheli apha.

Umqobo wesibini ojongene neenkampani zezithambiso kukuba amasebe afanelekileyo olawulo lukarhulumente enze uhlolo olungacwangciswanga kwizinto zokuthambisa ebezisasazwa ukuqinisekisa uphuhliso olusempilweni nolucwangcisiweyo lwemarike.Umzekelo, ingaba ilothe, i-arsenic, i-mercury, i-bacterial colony count, i-p-phenylenediamine, i-disperse idayi, njl.njl. kwiimveliso ze-cosmetic zigqithise umgangatho, okanye kukho izinto ezivaliweyo ezifana ne-meta-phenylenediamine kunye ne-phthalates.Ngamanye amaxesha le misebenzi yovavanyo ikwaphathiswa iilabhoratri zamaziko ovavanyo lomntu wesithathu.Ngokufanayo, oku kufuneka kuqinisekiswe ngovavanyo lwesampulu phambi kokuba ingxelo yokuhlolwa komgangatho ikhutshelwe iinkampani zezithambiso kunye neemveliso zazo ngokwemigaqo yomthetho.

Akunzima ukucinga ukuba ukuze uzuze inzuzo yokuqala kukhuphiswano lweemarike ezinobunzima, njengoko i-frequency entsha yophando kunye nophuhliso lweenkampani zokuthambisa ziqhubeka nokukhula, oku kuthetha ukuba umthwalo webhubhoratri uya kwanda.

Nangona kunjalo, nokuba yilabhoratri yenkampani yezothambiso, ilebhu yesebe likarhulumente, okanye ilabhoratri yovavanyo lomntu wesithathu, umsebenzi wovavanyo lwezithambiso unzima kakhulu, kwaye akunakuphepheka ukwandisa inani lezixhobo zovavanyo ukuze ukuphucula ukusebenza kakuhle.Ngokukodwa ukwenzela ukuba kuqinisekiswe ukuchaneka kweziphumo zovavanyo, ukucoceka kweglasi esetyenzisiweyo ekuvavanyeni kufuneka kuxazululwe kuqala.Ujongene nalo mngeni, indima yeIwasha yeglasi yelabhoratriiye yabaluleka ngakumbi nangakumbi.Ngenxa yokubaiwasha glassware oluzenzekelayoayinakubonelela kuphela ngomgangatho omkhulu, onengqondo kunye nokucocwa ngokucokisekileyo kwezinto ezingcolisa i-glassware yelabhoratri, kodwa ikhuselekile kwaye ikhuselekile ngakumbi kokusingqongileyo ngexesha lokusetyenziswa.Idatha efanelekileyo erekhodiweyo inokunceda ukunika ireferensi esebenzayo xa kuvavanywa umgangatho wezinto zokuthambisa.

Musa ukuvumela ukutotoswa kube buhlungu.Ukuphelisa ukongezwa ngokungekho mthethweni kwezinto ezithintelweyo nezithintelweyo, kwaye uqinisekise ubunzululwazi, uzinzo kunye nokusebenza kakuhle kweemveliso zokuthambisa.Oku kuchaphazela amalungelo kunye nokhuseleko lwabathengi, kwaye kulapho abavelisi kunye nabalawuli bazalisekisa izibophelelo kunye noxanduva lwabo.Isitshixo sokhuseleko lwezithambiso sixhomekeke ekuchanekeni kweziphumo zovavanyo lwebhubhoratri.Kuphela ngokufumana uhlalutyo lokwenene lovavanyo kunye nezigqibo sinokuthi sibe nelizwi lokwenyani.
